“…Although the link between norms and personal behavior seems fairly well-established,, the specific influence processes involved remain relatively unclear. Much of the social norms research to date demonstrates or presumes a passive influence process, whereby merely perceiving a focal norm (Cialdini, Reno, & Kallgren, 1990; Joly, Stapel, & Lindenberg, 2008), via exposure to the behaviors of close friends or proximal others (Capone, Wood, Borsari & Laird, 2007; Cullum, Armeli, & Tennen, 2010; Goldstein, Cialdini, & Griskevicius, 2008) is enough to guide a person’s own subsequent behavior. That is, the influence of the social norm on personal behavior in these instances requires no direct pressure upon a person to change his or her behavior, and makes no attempt to persuade or request a person’s compliance with a norm; however, in many social settings, norms may also be enforced or actively promoted by other people present in the environment.…”
